IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 185,787, dated December26, 1876; application filed September 28, 1876.

To all whom it may concern:

Be it known that I, FRANK SEoLLAE, of Otsego Lake, in the oo unty ofOtsego and State ofMichigan, have invented a new and useful Improvementin Pumps, which improve- 'ment is fully set forth in the'followingspecilication, reference being had to the accompanying drawings, inwhich- Figure 1 is a front View of my improved pump, partly in section,and partly in side elevation. Fig. 2 is a central section of the upperpart, in detail 5 and Figs. 3 and 4 are horizontal sections of the samein the line w ac of Fig. l, representing two select positions ot' thestop-cock.

My invention relates to force pumps or pumps with solid pistons; and thesame consists in certain constructions, combinations, and arrangementsof parts, hereinafter described and specifically claimed, whereby theobject of producing a cheap pump .of simple construction, greatdurability, and easy of operation is more eii'ectually accomplished, andat the same time applicable to a variety ot purposes for whichheretofore only pumps of complicated construction and of high price havebeen used.

In the drawings, A A represent two pumpbarrels, which are provided attheir bottom with valve-plates B, having ball-valves I; in.

valve-cages b', and tube ends B' with screwthreads to connect withsuction pipes or hose. Above the said plates B the pump-barrels areprovided with openings a and tubular extensions A', wherewith they arefastened to T- shaped connections C, the bore of which is larger thanthe holes a, so that an elongated sliding plug-valve, D, of the samediameter therewith, and properly formed at the ends, may close either ofthe said holes a alternately, and also close the bore of the pump whilecrossing the same in a right and left hand direction. The holes a mayfor that purpose be provided with valve-seats a. The upright part of theconnection O is provided with a ball-valve, c, in a valve-cage, c',which serves as a check-valve to the pump-stock E above the saidconnection. The pump-stock E and the connection O are attached to eachother by screw-thread, as shown in the drawings, or by similar means,and the upper part of the said pump-stock may be closed by a verticalcock, F, with two openings, ff', standing at a right angle to eachother. The said cock F is fitted into the material of the pump-stock E,which latter has two outlets, c c1, in the same level with the holesff', and diametrically opposite each other, one of which outlets, el,may be provided with a serpentine mouthpiece, e2, for the purpose ofordinary supply in yards, stables, kitchens, and so on, while anothermouth-piece, e3, is fastened to the outlet e, and is used in connectionwith pipes or hose for the purpose of conveying the water to a greatdistance or height. In the sectional View of Fig. 3 the cock F is turnedto the left, and the port f opens into the outlet e, -while the outletel and the port j" are closed. If the cock F is turned to the right theport f will open into the outlet el, and the portf and the outlet e areclosed. lf the cock F is moved into a central position both ports f fwill partly open into both outlets eel, and supply water on both sidesof the pump. Above the pump-stock E is a cap, G, fastened to itin theusual manner ot' fastening, which bears upon the top of the cock, andthereby keeps ift firmly in its seat, leaving a small lateral space, g,open for the movements of the cockhandle F'. To the top of the said capG the fulcrum Gof the operating-lever H is fastened to which thepump-rods h are attached. To the lower ends of the pump-rods h theplungers I of the pump-barrels A are attached. The said plungers I workwithout packing, and are therefore provided with a very largefriction-surface and are tted pretty accurately into the barrels A.

Operation: When the right side ofthe lever H is moved down, the plungerI moves down and pushes the water in the barrel before it. rlhis, in thefirst instance, closes the valve b, and the water is thus forced throughthe side openings a, into the connecting-tube O. The plug-valve D ispushed against the abutment or valve-seat a at the end of the extensionA of the other barrel A, and the water lifts the valve c and rises inthe pump-stock E, enters the cock F, and passes through the portfintothe pipe e if the cock is turned to the left. At the same time thedescribed operation takes place the otherplunger rises and causes thevalve uy below it to rise and admit the socalled suction or supply waterfrom the well. The operation, which has taken place in both barrels Aand the connection C, is reversed when the motion ofthe lever Hisreversed.

The described pump may be made entirely of wood where metal is noteasily to be had; but the preference is given to metal, on account ot'its greater durability.

The efficiencyv of my improved pump would be the same if there werevulves of different construction; but the cheapest and most re liablevalves are ball valves.

The pump will work best under water, be cause the suction ofthe risingpluugers would not be impaired b v air leaking between its bearings downinto the barrel; but even above water this pump answers its purposebetter than all other pumps of that class I have yet seen, for itsupplies a continuous stream without friction in the barrels. and with aless number of valves, and without the disadvantage of extravalve-chambers below the pumpbarrels.

Having thus described my invention, what i claim, and desire to secureby Letter Patent, is-

1. The combination ofthe elongated plugvalve D, operating as specied,pu1np-sectiou C, cylinders A A, and barrel or stock E, substantially asand for the purpose described.

2. The cylindrical two-Way tubular valve F, arranged in seats ofthepump-stock E and cap G, and operated by a horizontal lever, F', in themanner and for the purpose described.

Witness my hand in the matter ot' my application for a patent for animproved pump this 26th day of August, 1876.
